Rancho Cucamonga's first responders strive to provide world-class community service and protection. Fulfilling this goal starts, as they say, at the top. We are proud to announce two recent changes in the leadership of these fine service organizations that are sure to preserve the outstanding reputation of both departments. Congratulations to the newly promoted Fire Chief Ivan Rojer and Chief of Police Donny Mahoney.

Fire Chief Ivan Rojer - The Fire District bid farewell to Fire Chief Costello in late November 2017. He retired after 32 years of service. The organization has since promoted Deputy Chief Ivan Rojer to its top leadership role.

Chief Rojer not only serves this community, but also calls Rancho Cucamonga home. He began his Fire District career in 1992, during which he also put himself through Paramedic school and earned a Bachelor of Science in Occupational Studies from Cal State University, Long Beach. He promoted through the ranks of Engineer and Captain before becoming Battalion Chief in 2009, and Deputy Chief of Operations in 2014. Chief Rojer also earned the State's esteemed Chief Officer Certification.

His passion and professionalism are evident through his servant leadership. He describes it as "making a difference because we care."

Chief of Police Donny Mahoney - Mahoney served in the Air Force as a Jet Aircraft Mechanic and worked in the private Aerospace sector before joining the San Bernardino County Sheriff's Department in 1992. He is a 26-year veteran of the department and his service includes over six years on patrol, four of those years on a motorcycle in the City of Rancho Cucamonga. He also served as a Homicide Detective, CSI Supervisor, and Commander of the Crime Lab, Twin Peaks/Lake Arrowhead communities, and the West Valley Detention Center.

As you can see, our new Chief brings a tremendous amount of law enforcement experience to the Rancho Cucamonga Police Department. He is committed to providing exceptional law enforcement services while developing healthy community partnerships that enhance the quality of life for all Rancho Cucamonga residents.

"The outstanding members of the San Bernardino County Sheriff's Department and the city of Rancho Cucamonga share a passionate commitment to the safety and well-being of the citizens of Rancho Cucamonga. With this strong and devoted relationship, I feel anything is possible," said Chief Donny Mahoney.
